Description

Abstract:

Zinc plays an important role in normal growth and development in the first 3 years of children's life; it also has a significant activity in the immune system. Therefore it is one of the most important essential trace elements in infant nutrition. It's necessary to supply infant formulas by trace elements like zinc in order to make their composition similar to that of human milk. Zinc contents were determined in 25 infant milk formula samples from different manufactures commercially available in Syrian markets using flame atomic absorption spectrophotometer. Two extraction methods were conducted, the first involved the use of trichloroacetic acid, and the second one was accomplished by dry ashing method. Both methods were compared according to the extraction recovery and the repeatability. The study showed that extraction using trichloroacetic acid was rapid, easier and had a high recovery.
